Dear all, I'm new to linux modem installations. I have already compiled 2 modem = drivers, one for Lucent Winmodem and one for PCTel. I firstly install the PCTel driver and the device ttyS_PCTEL0 setup = successfully. However, after I installed the Lucent modem driver and = reboot, I can only find out the Lucent modem (ttyLTM0) but the PCTel = (ttyS_PCTEL0) disappears. However, the module of PCTel modem is already = loaded. What configurations I still need to make for the successful = installation? Thanks for your help. Best Regards, Jacky
